Summary
Sfinks Ltd
telecom residential russia
The AS handle SMEDIA-AS is held by Sfinks Ltd.
What it's used for
- The address space carries subscriber traffic, as indicated by reverse DNS entries pointing to
leadertelecom.ru(e.g.,37.230.142.64.leadertelecom.ru). - The network announces 1024 IPv4 addresses across 3 prefixes and has 1 observed neighbour, a ratio consistent with an access or eyeball network rather than a transit provider.
- Traffic from this AS consists of residential or small business subscriber connections served by the operator's telecommunications infrastructure.
Notable
- Registrants for all announced prefixes (
ORG-SL923-RIPE,Sfinks-NET) align with the AS holder, Sfinks Ltd. - The inventory consists of three distinct IPv4 blocks:
91.230.62.0/23,37.230.142.0/24, and37.230.250.0/24, with no IPv6 prefixes in inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-12, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 453 networks and 1,848 prefixes, as published 2026-11-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
